Thear modify sbs80 main pump boss
If i understand you correctly you have changed out the original pump in the 311B which would of been a Kawasaki K3V63DT to a SBS80 unit and now you need to connect the power shift solenoid. The SBS unit has its own integrated solenoid and the K3V unit did not. The K3V had a remote operated solenoid sending its signal to the pump. See SBS attachment. Port 2 is constant pilot supply for powershift and port 9 is a test point measuring port best regards
Yes I understand boss many many thanks
